It’s the ultimate comfort food, ideal for cold days, casual family meals, or whenever you want something both nostalgic and satisfying.
Ingredients:
- 4 large slices of bread (preferably white or sourdough)
- 4 tablespoons butter
- 1 can (10.5 oz) condensed tomato soup
- 1 cup shredded cheddar cheese
- 1/2 cup mozzarella cheese, shredded
- 1 cup milk
- 1/4 teaspoon garlic powder
- 1/4 teaspoon onion powder
- Salt and pepper to taste
- Fresh basil or parsley (optional, for garnish)

Instructions:
- Prepare the Grilled Cheese: Begin by making the grilled cheese sandwiches. Butter both sides of the bread slices, then grill them in a skillet over medium heat until golden brown on both sides and the cheese inside is melted. Once done, remove the sandwiches from the skillet and set them aside to cool slightly before cutting them into bite-sized squares.
- Make the Soup Mixture: In a separate bowl, combine the condensed tomato soup, milk, garlic powder, onion powder, salt, and pepper. Mix everything together until smooth. This will serve as the base for the casserole and give it a creamy texture that ties everything together.
- Assemble the Casserole: Preheat your oven to 350°F (175°C). In a greased 9×9-inch baking dish, layer the grilled cheese squares evenly across the bottom. Pour the tomato soup mixture over the bread, making sure the bread squares are fully submerged in the creamy liquid.
- Add the Cheese: Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top of the casserole. This will create a rich, cheesy layer as the casserole bakes, adding flavor and a golden, bubbly finish.
- Bake to Perfection: Place the casserole in the preheated oven and bake for about 25-30 minutes, or until the cheese is melted, bubbly, and golden brown on top. The casserole should be firm and slightly crispy on the edges, with the flavors melded together perfectly.
- Serve and Enjoy: Let the casserole cool for a few minutes before serving. Garnish with fresh basil or parsley if desired for a pop of color and added flavor.
